Hi, we are on the right track now.. I am model railroading.. and one of the questions is always: did the last car of that train was still attached to it when the train left the tunnel? In other words, identification of the pieces of rolling stock is an issue.. this technology could be applied here!

Defensive steps could then be taken with the lawn cutting lazer to cut the Goat off at the knees thus preventing terminal damage to ones prize roses................ The Goat saga continues......... Cheers Steve.................

Brilliant Steve.. the lowering of the goat's altitude we will use as a confirmation that the goat is stopped in her evasive addiction.. (goats are infamous in this subject.. a French proverb says: a goat makes you swear) but how do you get the z information from the kunstkopf? This last question is on topic again, Wim.

<Wim writes in part> > ... but how do you get the z information from the kunstkopf? Yeah, I nearly jumped on that one, but he's right. Each kunstkopf is binaural and can triangulate on the goat. Having two kunstkopfs gives two triangles. Knowing the distance between kunstkopfs gives the necessary information to triangulate the "z" dimension. And get a kopfache <g>.

I hear real trains use >bar codes to label cars. They tried that, but the bars often were obscured by dirt. So they use RF "tags" now. The train-mounted part modulates a serial number onto the signal reflected from a track-side radio transmitter. This is different from the anti-shoplifiting tags since it is necessary to uniquely identify each car. The anti-shoplifiting tag detector only identifies if a tag is present or not. The presence of a train on the track is of course detected by the wheels shorting the two rails together.
